newbie- general constraint solver?

[Neal D. Becker]

I don't really know anything about faces-pm. Just wondering. Can this solve general contrained problems? For example, scheduling speakers for rooms at a conference.

Here is small example you can try out:

-- coding: utf-8 --

from faces import *
from faces.lib import report
from faces.lib import gantt
from faces.lib import resource

class Room1(Resource):
pass

class Room2(Resource):
pass

class Room3(Resource):
pass

def Scheduling():
resource = Room1 | Room2 | Room3
speaker = ""
start = "2005-1-16"

def PYHS1():
    title = "Applied Quantum Mechanincs"
    length = "1H"
    speaker = """Schrödinger"""

def PYHS2():
    title = "Relativity And TimeTravelling"
    speaker = "Einstein"
    length = "1H 30M"


def PHYS3():
    title = "Freewill and Relativity"
    speaker = "Einstein"
    start = up.PYHS2.end
    length = "1H"

def CPS1():
    title = "Tables are out"
    speaker = "Date"
    length = "1H"

def CPS2():
    title = "The Psychology of an CPU"
    speaker = "weinberg"
    length = "1H"

project = BalancedProject(Scheduling)

class Gantt(gantt.Standard):
data = project
sharex = "share1"

class Report(report.Standard):
data = list(project)[1:]

def make_report(self, data):
    for t in data: 
        yield (t.name, t.title, t.speaker, t.start, t.end, t.booked_resource)

class RoomLoad(resource.Standard):
data = project
sharex = "share1"

def modify_bar(self, bar_widget, row_widget, task):
    bar_widget.text("speaker: %s\n" % task.speaker,
                    LEFT + 2*HSEP, TOP - 2*VSEP,
                    horizontalalignment="left",
                    verticalalignment="top",
                    color="white")

You can probably do this but keep in mind, faces is a project management tool. Maybe there is a tool in the web, that fits better.
